【摘要】 本文从永磁材料及黏结永磁体的不同分类方法出发,采用具有我国自主知识产权的新型NdFeN永磁粉末作为黏结永磁体的磁性粉末填料,研制出一种新型的黏结NdFeN永磁体。从NdFeN永磁粉末、压延成形法制作黏结NdFeN永磁体的黏结剂、配合剂和制备工艺到其市场前景的展望等等方面进行了综述,并从具体实验方法制备出的新型黏结NdFeN永磁体的磁性能和SEM照片看出,这种新开发的新型黏结NdFeN永磁体具有很好的磁性能和优良的黏结剂与磁粉黏结效果。认为黏结稀土NdFeN永磁体具有较强的开发价值和应用价值,在未来的市场中具有很强的商业竞争力。更多还原

【Abstract】 From the classifications of permanent materials and bonded permanent magnets, we have produced a newly type bonded NdFeN permanent magnets using the NdFeN powder with patents of our country . The magnetic powder,bond agent and match agent,manufacturing processes,and market predict are discussed from this newly type magnets’ magnetic properties and SEM fractography,we can see that they have excellent features. We also can draw a conclusion that bonded NdFeN permanent magnets are worthy exploited.更多还原
